Hashes are great for storing named data, but if you want more than one entry
for a name, you have to use a list of pairs. Even then, this is really boring
to write:
@values = (
foo => undef,
bar => undef,
baz => undef,
xyz => { ... },
);
With Data::OptList, you can do this instead:
Data::OptList::mkopt([
qw(foo bar baz),
xyz => { ... },
]);
This works by assuming that any defined scalar is a name and any reference
following a name is its value.

Change the way Perl modules are installed, update the default Perl to 5.18.
Before, we had:
site_perl : lib/perl5/site_perl/5.18
site_perl/perl_arch : lib/perl5/site_perl/5.18/mach
perl_man3 : lib/perl5/5.18/man/man3
Now we have:
site_perl : lib/perl5/site_perl
site_arch : lib/perl5/site_perl/mach/5.18
perl_man3 : lib/perl5/site_perl/man/man3
Modules without any .so will be installed at the same place regardless of the
